Section I – Introduction
MN06135 Issue/Rev. 1.3 (6/17) 1
This manual is to be used for the installation of the
AccuLoad III Electronic Preset Controller with Accu-
Load III firmware. The manual is divided into the fol-
lowing sections: Introduction, Pre-Installation Con-
siderations, Installation, Diagrams, Maintenance,
Completing the Installation, and Related Publica-
tions.
Receipt of Equipment
When the equipment is received the outside pack-
ing, case should be checked immediately for any
shipping damage. If the packing case has been
damaged, the local carrier should be notified at once
regarding his liability. Carefully remove the unit from
its packing case and inspect for damaged or missing
parts.
If damage has occurred during shipment or parts are
missing, a written report should be submitted to the
Customer Service Department, FMC Technologies
Measurement Solutions, Inc., 1602 Wagner Avenue,
Erie, Pennsylvania 16510.
Before installation, the unit should be stored in its
original packing case and protected from adverse
weather conditions and abuse.
Warnings and Precautions
Before you begin please read all of the following
warnings and cautions to reduce the risk of injury,
equipment damage or malfunction.
Emergency Shutdown – The AccuLoad has an ex-
tensive set of built-in safety features.
IMPORTANT: The AccuLoad should never be relied
upon to act as the primary safety system control for
the flow valve and pump controls, i.e. emergency
stop, overfill, ground protection, etc. These should
always be handled by separate systems specifically
designed for that application. For example, Safety
systems specifically to meet SIL requirements. Any
power control circuits from these external systems
shall be wired in series ahead of the AccuLoad to
remove power to the ancillary devices.
Hazardous Voltages – There are hazardous volt-
ages involved in the installation and maintenance of
the AccuLoad and only qualified individuals should
perform installation.
Haza
rdous Locations – The S and Q models are
approved for use in an explosive (Class I, Div. I,
Groups C & D and Zone 1 Ex d ia, IIB Gb) atmos-
phere but there are specific installation methods re-
quired to produce a comprehensive explosion-proof
system. This manual provides guidance for the Ac-
cuLoad installation only. In general, keeping the
front cover bolted close in accordance with the in-
structions in Section VII is the key to maintaining ex-
plosion protection.
Any modification of the AccuLoad housing inval-
idate the hazardous location rating of the Accu-
Load.
• Do not replace the bolts in the front cover
except with those supplied by the manufac-
ture. Using unapproved bolts invalidates the
explosion-proof rating of the enclosure.
• Do not drill or machine the housing.
• Do not attempt to replace the touchscreen or
glass except as part of the factory supplied
assembly.
Electrostatic Discharge Precautions – The elec-
tronic components in the AccuLoad are susceptible
to damage by static discharge. To minimize the risk
of damage, the following precautions should be fol-
lowed:
• Before touching a circuit board with hands or
tools, personnel/tools should be grounded
using a wrist strap.
• Avoid touching components or traces on the
circuit boards and handle by the edg-
es/mounting holes.
• Circuit boards should be kept in conductive
bags when not installed.
ATEX / IEC Installations – There are special re-
quirements for ATEX approved installations. Please
refer to Section III for a detailed list of the specific
requirements.
RF Radiation - The AccuLoad generates, uses, and
can radiate radio frequency energy and, if not in-
stalled and used in accordance with this Manual,
may cause interference to radio communications. It
has not been tested to comply with the limits pursu-
ant to Part 15 (CFR 47) of FCC Rules, as electronic
control equipment utilized by an industrial complex is
exempt from the rules.
